Mixtures which can be crosslinked by photopolymerization and are based on binders, photopolymerizable monomers which are compatible with these, photoinitiators and thermal polymerization inhibitors contain, as the binder, polymers of the formula I <IMAGE> I where Pol is a radical of a block copolymer prepared by sequential anionic polymerization of conjugated dienes and vinyl aromatics, R1 is a vicinal alkanediyl group, R2 is a divalent hydrocarbon group of 2 to 20 carbon atoms, X- is an acid anion, M is a metal cation, a metal cation complex or cation of an amine, and a and n are each an integer from 1 to 10. |
